arm64: dts: rockchip: add linestate check dis quirk for rk3399 dwc3

Browse Source 
rk3399 dwc3 has a problem that USB 2.0 MAC lineState not
reflect the expected line state (J) during transmission.
Add this quirk to add the ipgap between (tkn to tkn/data)
with 40 bit times of TXENDDELAY, and linestate is ignored
during this 40 bit times delay.
